LIQUID-HYDROCARBON DISTRIBUTER FOR ROADS.

1,114.,eie.

county of Albany, State of New York, re

spectively, have invented certain new and useful Improvements inLiquid-Hydrocar-I bon Distributors for Roads, of which the following isa specification.

This invention relates to awheeled-tank device for distributing liquidupon a surface or region traveled over.

The device is designed more particularly for use in distributing liquidasphalt or the like over crushed stone beds in road-building, or oil ontop of the finished road to bind the surface together.

One of the objects of the invention is, in a simple, low-cost, one-mandevice, adapted for operation by unskilled labor, to provide convenientand reliable means for opening and holding open the valve mechanismcontrolling the discharge of the tank.

A further object is to provide an improved form of discharge comprisingtwo chambers, controlled by separate valves and having dischargeopenings of different sizes, whereby streams or sheets of the liquid ofdifferent, fixed thickness may be permitted to flow from the device,according to which valve or set of valves is opened; in this way doingaway with the necessity for adjustment of a single discharge opening, inorder to secure variation in the quantity of liquid distributed within agiven time.

A further object is to provide protection for the valves and to preventimpurities or clogging matter from entering the valve openings, by meansof a suitable capacious chamber containing the valves and having an openside communicating with the main interior of the tank and guarded by aremovable strainer.

Further objects of the invention will become apparent as thespecification proceeds.

With these objects in view the invention consists in certainimprovements, parts and combinations, the preferred embodiments of whichare illustrated in the accompanying drawings which are hereby made apart of this specification.

In the said drawings :-Figu1'e 1 is a top plan view; Fig. 2 is a partialsection on the line 2-2 of Fig. 1; Fig; 3 is a front eleva plate 25.idle 28 at its top. for facilitating removal. The valve-controlledopenings. 21 and 92ers Specification of Letters Patent.

tion; and Fig. 1 is a fragmentary sectional view showing a modifiedconstruction of valve-operating means. i

In these views the numerallO indicates a tank, preferably of oblongrectangular shape. This tank is preferably supported by means of a pair01' wheels 11, which may be mounted loosely on the ends of a rod 12,that passes loosely through a tube 13 connecting the side walls of thetank and acting as a brace therefor. The tank is provided at its rearend with two discharge chambers 11 and 15, which are located immediatelybelow the rear part of the tank, in rear of the wheels, the bottom ofthe tank forming the tops of the chambers. The chambersare triangular incross-section, being formed by downwardly-inclined, converging, frontand back walls 16 and 17 and a central vertical wall 18, which extendsdownward from the bottom of the tank and completely divides theinteriors of the chambers from each other. The end portions of thedischarge chambers preferably extend beyond the wheels, and are providedwith suitable end walls. The walls 16 and 17 terminate at their loweredges at unequal distances from the central wall 18, so as to affordadjacent slotted discharge openings 19 and 20, of different widths. Thecentral wall extends downward below the front and back walls, so as toafford a depending lip from which the fluid will flow. Each dischargechamber communicates with the interior of the tank by means of one ormore openings 21., 22.

valves are protected by a horizontal plate or.

partition. 25 within the tank. this partition preferably extending fromside to side and to the back thereof. The capacious chamber thus formedfor the reception of the valves has its open front side incommunicationwith the main interior of the tank, and this opening is guarded by meansof a removable strainer 26. This strainer occupies an inclined position,resting at its lower end against an inclined ledge 27 projecting upwardfrom the tank bottom, and at its upper end against the forward edge ofthe The strainer has a suitable hanpreferablv staggered with relation toeach other. When this is the case horizontal.

bafile plates 29 and 30 are employed in the two discharge chambers 1 1-and 15, to dis tribute the fluid evenly to the slotted dischargeopenings 19 and 20.

In the form of the invention shown in Figs. 1 to 3 tne tank is providedat the front with two sets of handles for pulling the same. One pair ofhandles 31 are formed by forwardly-projecting shafts which are securedrigidly to the sides of the tank. These shafts are so arranged that aman. may walk between them comfortably with one hand grasping eachhandle, in the position indicated by dotted lines at A in Fig. 2. Thesecond pair of handles for pulling the tank are pivotally connected withthe tank, and have connections with the valves 23 and 24, whereby thechanged relation between these handles and the tank when the latter isdrawn by means of the former causes the valves to open and remain open.In the construction illustrated the handles 32 are normally at adifferent elevation from the handles 31, so that the handles 32 must bemoved in order that the operator may draw the tank conveniently by meansof them. This movement of the handles results in the opening of thevalves. .he handles 32 consist of bulb-shaped grips, which are pivoted33 to brackets secured to the forward ends of the handle shafts 31.These handles normally project downward, and are swung upward to theposition indicated by dotted lines at B when the operator grasps themfor the purpose of pulling the vehicle. The handles 32 have rightangular extensions 34, to which are pivoted the forward ends of linksThese links extend rearward to points adjacent to the front of the tankand are pivoted at their rear ends to the lower ends of cranks 36 whichare secured to a rock shaft 37 ournaled in hangers or brackets in frontof the tank on the handle shafts 31. A central upward-extending curvedlever arm 38 is secured to the rock shaft 37, and is connected by a link39 with the forward end of a valve-lever 40 within the tank. This lever10 is in the nature of a frame approximating in width the interior ofthe tank, so that the interior of the tank is not obstructed. It ispivoted intermedate its ends on a rod or shaft 70, which is securedendwise to the sides of the tank and serves to brace the same. The rearend of, the frame-like lever is formed by two bars 41, 42, to which maybe connected the valve stems l3, -Either valve or set of valves may bedisconnected from the lever by removing the pins t5 which pass throughregistering openings in ears 16 on the bars and in the upper ends of thevalve stems. The valve stems are guided in openings in the plate 25 andalso in openings in braces 47. The lower ends of the valve stems areconnected loosely with the valves 23 and 24:, so

as to facilitate the action of the valves in finding their seats.

A. spring 53 is provided for restoring the parts and closing the valves23 and 24. This spring may be placed at different points, but isillustrated as connected at one end to a lug 5-1 on the lever arm 38 andat the other end to the front of the tank.

The device is preferably provided beneath the tank with a fire chamberl8 having a hinged door a9, and a chimney 50 extending upward throughthe tank. The tank is preferably provided with two hinged covers 51 andThese features are disclosed in our prior Patent No. 1,028,288 datedJune 4, 1912.

A gage is provided at the front of the tank 10, in alinement with theouter end wall of the discharge chambers 14 and 15. By means of thisgage the operator is enabled to guide the device along the margin of apreviously oiled strip. A bracket 66 which .is clamped by a set-screw 67onto the shaft-handle 31 holds at its outer end the said gage-rod 65 invertical adjustment by means of a set-screw 68. v

In operation, when it is desired to pull the tank with the valvesclosed, the operator takes his position between the shafts and graspsthe handles 31. When it is desired to open the valves and to draw thetank with them held open, the operator shifts his grasp from the handles31 to the handles 32. The position of the handles 32 necessitates theirbeing swung upward by the operator in order to pull the tank in a normalmanner. This movement results in the opening of the valves 23 and 24.The changed positions of the various pivotal connections is indicated bysolid circles in Fig. 2. The movement of the handles 32 is limited byany suitable means, such as the lever arm 38 abutting against theforward edge of the tank. This operation places the spring 53 undertension, so that the spring restores the parts and closes the valveswhen the operator releases his grasp upon the movable handles 32. Thefluid may be discharged from either or both of the discharge orifices 19and 20. For the first spreading upon the stone the valve 23 isdisconnected from the lever 40, so that the chamber lat is cut off fromthe interior of the tank, and the discharge is only through the widerslot 20. For the top coating the valve 24: is disconnected from thelever 10, so that a thinner stream is discharged through the slottedorifice 19. hen the valves of both chambers are opened, a stream ofmaximum thickness is allowed to flow through the two adjacent slotteddischarge openings. If desired, one or both of the slotted openingsmight be regulated by a slide, 71, and as disclosed in our priorapplication aforesaid. WVhen the operator grasps the handles 32 to drawthe tank and open the valves, the forward and heavier part of the tanktilts downward to a certain extent. For this reason the bottom of thetank is inclined downward and rearward, so that the contents will alwaysfind their way to the discharge chamber at the rear. hether the tankactually tilts or not when the handles 32 are grasped, the overbalancingof the tank at one side of the axle assists in holding the valves open.

In the form of the invention shown in Fig. 4 the shafts 31*, whichafford handles at their forward ends, are pivoted to the front of thetank at 60. The rear ends of the shafts are connected with the valvelever 40 by means of the link (31, which is pivoted at opposite ends tothe shafts and to the lever 40. The shafts 31 are normally lockedagainst pivoting by means of a pivoted catch 62, which engages with thepivot rod 63. When this catch is released, the part of the tank inadvance of the axle sinks by reason of being overbalanced, and thismovement results in the opening of the valves. A stop (34: limits theextent of relative movement between the tank and the shafts 31 Havingdescribed our invention, what we desire to secure by Letters Patent andclaim is 2-.-
